Amanita fulva

Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)

Amanita caesareaAmanita     Genus
Fruiting body having a combination of some of the following characteristics:
Stalk growing out of a cup of cottony tissue called a volva (all white-spored mushrooms with a volva go here)
Cap with scattered patches or flakes of the same sort of tissue as the volva (see second picture), easily peeled off
Annulus (skirt-like ring on stalk)

Amanita V3Vaginatae     Section
Cap margin distinctly striate in maturity
Either (most commonly) annulus absent and colors brown or grey, or
(rarely) annulus present and colors bright: red, orange or yellow
Volva sack-like in some species, in others clamped tightly to the stem, leaving traces in bands of color on the stalk

Amanita fulvaVaginatae     SubSection
Cap usually some shade of brown or gray, occasionally white
Annulus absent, but there may be strangulated zones on the stem
Universal veil material generally not present (or only occasionally) on the cap
Volva sac-like, or clamped tightly to the stem

Larger Vaginatae     Stirp
Cap more than 1 1/2" across at maturity
Basidia mostly four-sterigmate

Amanita fulva     (Ja.C. Schaeffer: Persoon) Persoon

Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page.
If there's just a few words or a microscopic feature here, a more thorough description can be found above.

Microscropic Characters


When I first wrote this entry, I wrote:
"The stipe of Amanita fulva is usually much paler than the ones in the picture - - these may actually be a different species
The volva on this species is supposed to be ample and saccate, but it seems to be fragile, close to the stem, and in practice it is often almost absent."
Since then, I've learned that Rod Tulloss doesn't consider any of our American "Amanita fulva"s to be the "real", European Amanita fulva. So I'll be putting up more accurate names and descriptions as soon as someone comes up with them
